T0 a/ZZ whom, it may con/cern:

Be it known that I, HENRY W. AVERY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Seats for Harvesters orthe Like, (Gase 13,) of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings.

This invention relates to pressed-steel seats such as are used onvarious agricultural machines, as harvesters, cultivators, hayrakes, &c.

Its object is to provide a seat which while being simple in constructionshall have the metal disposed where it is most needed, so that anequally strong and durable seat may be made from less material, therebyreducing the cost. y

These seats are commonly supported centrally on a suitable spring-bar,and the tendency to break comes at the center portion adjacent to thesupport. To strengthen the seat at this point, it has been customary tocorrugate it; but as in stamping seats of sheet metal it isimpracticable to have the` original sheet thicker at one point thananother the whole seat has been made heavier than is necessary, so as tohave the right thickness for this center portion. The present inventionis designed to overcome this, providing a simple, efficient, andreinforcingplate at the center which shall so strengthen the seat atthis point that the total weight of the seat and the reinforcing may beless than the corrugated seat alone. I 'secure the reinforcing to theseat by suitably-disposed rivets, while in order to prevent the seatturning on its supporting-bar without employing additional members Iintegrally depress the reinforce to form a downwardly-extending stop forthe supporting-bar. This stop is preferably made by means of dents madein the upper surface of the reinforce, which dents on the under sideengage the bar and limit the position of the seat thereon. The inventionconsists of a seat so arranged and constructed.

The drawings show my improved seat.

Figure l is a bottom plan of the seat and its supporting-bar. Fig. 2 isa vertical section thereof on the line 2 2 of Fig. 1, and Fig'. 3 is afragmentary cross-section on the line 3 3 of Fig. 1.

As shown in the drawings, the seat proper is designated A. It isstampedfrom-a single piece of sheet metal into desirable form. Its centerportion a is iat, as shown. Directly beneath this center portion is areinforcingplate B, which is preferably circular. This reinforcing-plateis made of sheet metal and has in its upper surface dents b, whichthereby form integral projections on the under side of the plate. Theseprojections, of which there are preferably four in number, are solocated as to engage the edges of the supporting spring or bar C. Thereinforcing-plate B is held to the seat itself by suitable countersunkrivets D. The seat, with its reinforce, is held to the bar by thecentral bolt E and nut e.

With such a construction as described the seat proper may be made ofvery light material and the reinforcing-plate of vmaterial of the properthickness, according to the weight and wear, whereby the total weight ofthe seat and reinforce by being more efficiently placed are less thanthat of a seat made in one piece. The rivets D are easily put in placeand are unobjectionable, While the integral bosses or projections befficiently define the position of the seat.

l. A seat made of sheet metal and reinforced by a plate which is rivetedthereto and has a downwardly-extending integral projection adapted toengage the supporting-bar, substantially as described.

2. A seat composed of sheet metal combined with a sheet-metalreinforcing-plate beneath the central portion of the seat and riveted toit, said reinforcing-plate having downwardly-extended bosses formed bydents in the upper surface of the plate, whereby the position of thesupporting-bar is defined, substantially as described.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

HENRY W. AVERY.
